Selenium May Protect Against Prostate Cancer
 (NY, Reuters Health, 5/4/04)

Dr. Haojie Li of Harvard Medical School in Boston, and team, analyzed data for 1163 men who had participated in the Physician’s Health Study. At the outset of the study, the participants had been cancer-free and had had their blood tested for, among other things, selenium. The investigators now compared these initial selenium levels for 586 of the subjects who later developed prostate cancer with the levels of the others who did not develop the disease. The researchers found that men with high selenium levels were less likely to develop advanced prostate cancer. These findings suggest that selenium supplementation may slow down cancer progression, thereby decreasing the risk of prostate cancer reaching an advanced stage.
